I built the top stretchers using 2 5/8 X 4/4 stock I shaved down to 7/8. Then I cut a 3 ¾ tenon on each end.
And a quick clean up.
The lower stretcher is 7” x 7/8 with a 3 ¾ tenon on each side.
I took the end assemblies apart to cut the mortises in the lower splats and the upper part of the legs.
After drilling a series of holes to remove the bulk of the waist I clamped a block to the work piece to ensure my chisel cuts were straight.
And the same for the upper legs.
I used the same procedure with the stretchers, only this time I used a block cut to 7°. This is the angle for the wedges.
I cut the upper and lower wedges form scrap Walnut. After laying out the 7° angle I cut them on the band saw then fine tuned them with the plane.
Thanks fer looking.
